CMC Cardiac Medicine Certification questions with correct answers

Acute Coronary Syndrome (ACS): any group of clinical symptoms resulting from acute myocardial ischemia. CORRECT ANSWER begins with the rupture of atherosclerotic plaque, creating an injured area on the endothelium. platelet activation of the coagulation cascade and the formation of a thrombus over the injured area ensues CORRECT ANSWER restricted blood flow, cardiac ischemia and chest pain, the most common symptom of ACS. ACS is divided into three categories: CORRECT ANSWER unstable angina (USA) Non ST segment elevation MI (NSTEMI) ST segment elevation MI (STEMI). unstable angina (USA) CORRECT ANSWER no rise in cardiac biomarkers. If there is a decrease in left ventricular function secondary to cardiac ischemia, it returns to normal after the ischemia has resolved. Non-STEMI No evidence of ST elevation. CORRECT ANSWER Cardiac biomarker levels rise but the levels will not be high enough to render a positive test result. May be left ventricular dysfunction after NSTEMI resolves STEMI CORRECT ANSWER ST elevations will be present in different leads depending on injury location; a Q wave may be present. CK-MB and troponin are positive; high risk for left ventricular dysfunction.
